There was an unexpected courtside celebrity during Thursday night's game between the Miami Heat and Dallas Mavericks: Texas A&M QB and Heisman Trophy winner Johnny Manziel.

Courtside seats are anything but cheap and Steve Kerr seemed to say, without really saying it, that something unethical might have been going on. Listen to Kerr's comments below.

Later in the broadcast, Craig Sager came back to soften Kerr's stance and explain how Manziel came to have those seats. A transcript, courtesy of The Big Lead:

“We are in a 30-point game, time to clarify what could be a sticky situation," Sager said. "Johnny Manziel’s phone is getting inundated by text messages and tweets from friends and people wondering about a comment made by Steve Kerr about how he got these seats. Well, everything is legit. This is a birthday present that he bought for himself back on Dec. 6th. He’s a huge basketball fan. He loves LeBron James, has never seen him in person.

"So he has a birthday present that he purchased the ticket to come to the game, get the best seats he could possibly buy, and he is here to watch LeBron James. He practiced today in College Station getting ready for the Cotton Bowl, two and a half hour drive. He will be back at practice tomorrow; everything is legit.”
